Purpose

Used in conjunction with an “A” circulating mandrel to pressure test tubing.

Application

Set in a PSN or profile nipple to check the integrity before or after the tubing is run.

Operation

Install the PSN test plug in the desired nipple, this may be achieved by either wireline or by dropping the test plug and pumping it into place.

After pressure testing, lower the toolstring with a jar up / jar down pulling tool into wellbore and latch the fishneck of the A Circulating Mandrel jar up to shear the pin and slide fishneck up to expose equalizing ports. After the tubing string has been equalized, pull the PSN test plug from sealbore and remove toolstring from the wellbore.

Precautions

The BT PSN Test Plug holds pressure from above only, Ensure that the no-go on the test plug corresponds to the nipple to be utilized.
